Response To Comments On “Passivity-Based Control Of Saturated Induction Motors”, Levent U. Gökdere, Marwan A. Simaan, Charles W. Brice Jun 2004

Response To Comments On “Passivity-Based Control Of Saturated Induction Motors”, Levent U. Gökdere, Marwan A. Simaan, Charles W. Brice

Faculty Publications

Contrary to the claims made in the comments to our paper, the passivity-based controller developed for induction motors has already been tested on the same demanding trajectories used for the input–output linearization controller. The experimental results show that the passivitybased controller provides closer tracking of the same mechanical trajectory, when compared with the input–output linearization controller.

Hydraulic Characteristics Of Labyrinth Weirs, Corwin M. Willmore May 2004

Hydraulic Characteristics Of Labyrinth Weirs, Corwin M. Willmore

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Primarily, half-round crest labyrinth weirs were tested in this study with the side leg angle (a) ranging between 7 to 35 degrees. Historical data was primarily limited to quarter-round data. This study presents data and equations for estimating the discharge coefficient for labyrinth weirs with both half-round, quarter-round, and two Ogee-type crest weir shapes . A method is presented for comparing the flow capacity between weirs in order to determine the most efficient weir at a given Ht/P. For a labyrinth weir with the crest shape,# of cycles (N), and the cycle width (w) held constant, the discharge coefficient (Cct) …

Digital Design For A Sweeping Langmuir Probe Board, Omar Morales May 2004

Digital Design For A Sweeping Langmuir Probe Board, Omar Morales

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In-situ probing of the Earth's upper atmosphere has greatly contributed to the understanding of the ionosphere's variations and structures. The purpose of this research project has been to develop the digital component of a Swept Langmuir Probe that will be used on a sounding rocket to be launched through the equatorial ionosphere. The probe will make measurements of the plasma density and temperature in the ionosphere.

The digital component uses an FPGA to perform three main functions in parallel which are generating a sweeping voltage on the probe, sampling data channels, and communicating measured data to external devices. The FPGA …

A Turn To Engineering: The Continuing Struggle Of Technology Education For Legitimization As A School Subject, Theodore Lewis Jan 2004

A Turn To Engineering: The Continuing Struggle Of Technology Education For Legitimization As A School Subject, Theodore Lewis

Publications

In the long march from manual training, the subject which today we call technology education has always had to contend with the question of its legitimacy as valid school knowledge. In this regard, it shares a similar history of struggle with other subjects whose initial entry into the curriculum was based on a utilitarian rather than an academic rationale. Goodson (1983) documents such cases (e.g. geography and biology) showing how in their struggle for acceptance, the primary strategy of advocates was to try to enhance the academic bona fides of their subject. He explained that utilitarian knowledge is associated with …

Piezoresistive Properties Of Ito Strain Sensors Prepared With Controlled Nanoporosity, Otto J. Gregory, Tao You Dec 2003

Piezoresistive Properties Of Ito Strain Sensors Prepared With Controlled Nanoporosity, Otto J. Gregory, Tao You

Chemical, Biomolecular, and Materials Engineering Faculty Publications

A ceramic strain gage based on reactively sputtered indium-tinoxide (ITO) thin films is being developed to monitor the structural integrity of components employed in aerospace propulsion systems operating at temperatures in excess of 1500°C. The hightemperature stability and piezoresistive properties depend to a large extent on the thickness of the active ITO strain elements comprising these ceramic strain gages. Scanning electron microscopy of the thick ITO sensors revealed a partially sintered microstructure consisting of a contiguous network of submicrometer ITO particles with well-defined necks and isolated nanoporosity. It appeared that densification of the ITO particles was retarded during high-temperature exposure …
